Correct Answer:
Method / Topic: Biology
At anaphase, cohesin holding sister chromatids together is released and spindle microtubules move the daughter chromosomes toward opposite poles. Metaphase aligns chromosomes at the equator before this separation. For an MCAT biology problem, first identify the biological level being tested: molecule, cell, tissue, organ system, population, or experiment. Translate the stem into a cause-and-effect chain and use only the stated data plus a well-established biological principle. In physiology, follow the variable being regulated and decide whether the response is negative feedback. In genetics, separate parental from recombinant outcomes and show every probability step. In experiments, distinguish the manipulated variable, measured outcome, and appropriate comparison. Check units whenever a calculation is required. Then test every option against the mechanism; distractors often reverse direction, confuse correlation with causation, or name a true process occurring in the wrong cell, membrane, compartment, or stage. A final reasonableness check should confirm the
